Almost 100 years ago, Austrian Archduke Franz Ferdinand was shot dead in Sarajevo by Gavrilo Princip. The fallout from this assassination ultimately led to the start of the Great War (World War I). To commemorate this historical event’s centennial milestone, Google has launched a new portal dedicated to telling the story of this extraordinary time.

With support from several museums, this channel brings together a trove of World War I content like documents, letters, paintings, photographs and poems from soldiers. A visual presentation loaded with exhibits, visitors can take a four year virtual tour following the places and people that were a part of this historical period. A living archive, Google says it will continue to add content to this project as more organizations continue to honor World War I.
